[Contribution of L lactate and amino-acid enzymatic biosensors for the analysis of Frey syndrome]

Abstract

Twelve patients with Frey's syndrome after total parotidectomy for plemorphic adenoma were analysed using simultaneously 2 biosensors. Biosensors allowed for detection of L lactate and amino acid level on intact skin. The assay procedure and the results achieved with the simultaneous use of these 2 biosensors are presented. The L lactate biosensor appears to be an interesting tool for Frey's syndrome analysis. The sensibility of the amino acid biosensor is not sufficient enough to allow its use at time of Frey's syndrome analysis.
